Smartphones usually come with an AC adapter for charging. It plugs into an electrical outlet, and then plug the phone’s USB cable into the adapter.
The iPhone 4s has a really small AC adapter for USB-A, about the size of a walnut.
The Google Pixel 4a has a really big AC adapter for USB-C, about the size of a deck of cards.
Why is one AC adapter so much bigger? Something special about USB-C?
Thanks!

Modern smartphones have larger batteries and greater needs. That Apple charger is 5 watts. The Pixel’s is 18 watts.
A phone can still be charged with a lower wattage charger, but it will take longer.
